• Presently, the wild populations of gharials can only be found in Bangladesh, India and Nepal.

Explanation :

• Bio fencing is a unique and cost-effective method to keep wild animals away from residential areas and to protect agricultural crops and livestock in areas adjoining to forests.
• Plant species lemongrass, agave, rambans, and certain species of chilly and some other plant species have been identified to be grown in areas where wild animals enter residential areas and near forests.
• Bio-fencing with lemongrass will be done to prevent entry of elephants because elephants do not like the smell of lemongrass.
• Similarly, agave will be grown to deter elephant and wild boars. This biotic method is environment-friendly and harvesting of such plants can also be economical for farmers.
